A team of scientists from the University of Pennsylvania claims that they managed to patch up permanent teeth in children with the help of stem cells taken from baby teeth.

The team performed the clinical trial that involved 30 children treated with the new method and 10 children treated with the traditional method. They suggest that in the future it will be possible to use this technique to repair dental injuries and fix dead teeth in adults.

Songtao Shi, one of the research team, says: “This treatment gives patients sensation back in their teeth. If you give them a warm or cold stimulation, they can feel it; they have living teeth again. So far we have follow-up data for two, two and a half, even three years, and have shown it’s a safe and effective therapy.”
